This book is a compilation of training materials weeds and invasive plant management by SEAMEO BIOTROP and materials prepared by FORIS is a project "Removing Barriers of invasive Alien Management of Productive and protection Forest in Southeast Asia" implemented by PUSKONSER

Invasive alien species are a major and growing threat to biodiversity worldwide. The transport of organisms through increased levels of trade and tourism is leading to the widespread breaching of natural biogeographic barriers at unprecedented rates. Consequences can be severe, especially in naturally isolated ecosystems. Invasive alien species can cause the extinction of vulnerable endemic species, alter the structure and composition of communities, disrupt successional pathways, and lead to the loss of ecosystem services.

The effective management of invasive alien species is clearly a priority for biological conservation. This book provides strategies for managing such species at successive invasion stages, from prevention at the border to control of major infestations. It then describes the general approaches that are recommended for successful management of particular groups of invasive organisms in a range of environments. In each case, the ecological basis and practical requirements of invasive alien species management are addressed.

This book will be useful to a wide readership of students, academics, conservation practitioners, invasive species managers, legislators, and to the broader community concerned with biological conservation.
